Computer scientists and communications engineers review the current methodologies and mechanisms in the theory and practice of security, privacy, intrusion detection, and applied cryptography in smart grid communications. They cover vulnerabilities, threats, and attacks; authentication, privacy, and interoperability; intrusion detection systems and cryptography solutions; and smart energy and network management. The topics include denial of service attack on protocols for smart grid communications, secure interoperability in cyber-physical systems, a key management scheme for secure communications based on smart grid requirements, and modeling software-defined wireless sensor network architectures for smart grid neighborhood area networks.
